Letters Patent No. 96,547, dated November 9, v1869.

IMPROVEMENT 1N WATER-ELEVATORS.

The Schedule referred tointhese Letters Patent and making part of the sa'me.

erence marked thereon, making a part of this speciication, in which- Figure lis a plan View, and Figure 211s a transverse vertical section in the line am, iig. I.

To enable those skilled in the art to make and use my invention, I now-proceed to describe its construction and operation.

Similar letters in the drawings refer to like palts.

This inventionrrelates to a process of elevating water-"out of a well, by means of ahorizontal shaft, supported over the same, rotated by a crank, and bearing two wndlasses for hoisting and` lowering buckets, said windlasses being connected by abevelgear, so as to rotate them in opposite directions; and

y It consists in so attaching the crank tothe shaft that the crank may be inade. to operate as a lever for shifting the shaft endwise, back and forth, in and out of gear, alternately with each windlass, i'n order that both windlasses may be made to reverse their motions every time a bucket comes to the` surface; also, in combining with the shaft a stop to hold it in place, said st-op being operated by eachbucket in turn, so as to be displaced, and allow the shaftto be shifted as often as a bucket arrives at the surface.

In the drawings- A represents a well-curb, on the top of which is placed, in suitable bearings, a shaft, B, sustaining two windlasses, b b', the shaft being cylindrical, so as not to take the windlass around with it as it revolves, except as to the parts 'a a', which are foursided, and are intended to be introduced within the windlasses alternately, so that while one windl'ass is on one of the parts a', the other windlass may be on the cylindrical portion'of the shaft. v

A bevel-gear, O, connects the windlasses, which have cogs on their inner ends.

There isnothiug 'new-in the foregoing arrangement, nor the function discharged by the same, which is to cause the windlasses to revolve in contrary directions, so vthat as one hoists, thev other may lower its bucket; and also to cause the windlasses alternately to change direction, so as to lower the raised bucket, and raise the lowered one, without reversing the movement ofthe shaft.

The former object is effected by leaving one of the windlasses loose -on the shaft, so that it may be rotated in a contrary direction from the windlass that is fast to the shaft, by means of the connecting bevelear C.

vThe latter object is effected by shifting the shaft endwise, so as to throw it in gear with the loose windlass.

' The means by which the shaft lis shifted endwise are as follows:

The crank c is pivoted to an arm, c', projecting.

from the ratchet-plate d, through which the shaft passes. n

l rLhe ratchet-plate is attached Ato one end4 of a'tube that extends through the supporting-standard D, and to the other end of the tube is another plate, next to the opposite side of the standard.

Through the tube passes the shaft'B.

The tube `and ratchet d, withthe standard, form a firm fulcrum for the lever-crank c.-

By-moving the outer end4 of the crank outward,

the shaftis thrown into gear with the windlass b. l

By moving the outer end of the crank inward, the shaft is thrown in gear wit-li the windlass b.

In order to hold the shaft` in its place until the proper time for shifting itI attach to it rigidly a collar, e,`midway between the two square parts,

I also'provide a standard, E, rising from the well 'curb to the level of the shaft.

In the top of the standard E is pivoted, at right angles with the shaft, the blade h, the inner end of which is in contact with one side of the vvcollar e, and thus keeps the shaft in place.

To the outer end of the blade h is attached a rod, h', extending downward into the curb, and t0 the lower end of the rod is fastened a transverse bar, h, parallel with the shaft, and hung in the path of the buckets as they rise and fall.

As the ascending bucket approaches the surface, it catches the bar hf, and lifts it, which movement depresses the inner end of the blade h below the collar e, so that the.shaft may be shifted without ob stacle.

The shaft being shifted, the bucket descends, th bar h" follows it, and the blade .h comes up on the other side of the collar c, thus fastening the shaft.

The bar-rod and blade therefore form an automatic apparatus.

The bevel-gear serves not only to transmit motion from one windlass to the other, but also as a stop to prevent the crank from flying back with great velocity if the power is Withdrawn during the operw tion of hoisting.

What I claim as new, and desire to secure by Letters Patent, is

1. Attaching 'the crank c to the shaft B, in such a manner as that the crank may be operated as a 'leven to shift the shaft endwise, substantially as de-` scribed.

2. The combination of the shaft B, provided with its collar e, with the blade h, rod h', and bar h", as and for the purpose described.
